The new construction of the fourth construction phase of Optima Pharma consists of a production and assembly hall with an office wing in front of it. The assembly hall has a floor plan of around 55.0m x 60.0m. The hall does not have a basement and can be accessed by forklift trucks at ground level. The height of the building (including the surrounding parapet) is around 12.50m. The vertical roof and suspension loads of the hall are transferred via prestressed concrete or precast reinforced concrete beams, which rest on clamped precast reinforced concrete columns. The construction height of the pre-stressed precast concrete girders is a maximum of 1.70m, with a maximum span of 28.80m. The reinforced concrete columns, which are up to almost 12.0 m high, have dimensions of approx. 60 x 60 cm and were designed with pockets in the head area to ensure that the beams cannot tip over. The hall is braced against horizontal loads in both main directions via the clamped reinforced concrete columns. The low-slope roof of the logistics hall was planned as a lightweight construction and consists of trapezoidal sheet metal.

Adjacent to the northern side of the hall is an office building measuring approx. 7.20 x 60.40 m, which was constructed in solid construction. The office building has four floors (basement, ground floor and 1st and 2nd floors) and is approx. 16.0 m high, of which approx. 12.20 m are above ground. The ceilings are reinforced concrete slabs that rest on the wall panels of the two building cores and brace the building via this structure.
